Is the "Real World" a warren?

[Kierkegaurdian]

Barely Spoilers For Midnight Tides. I am halfway through Reaper's Gale, so if there are spoilers after that for my question, tell me to read it and find out!
In Midnight Tides, the Crimson Guard mage (forget his name) tells Seren Pedac that in some warrens, you can look into the sky and see other configurations of stars, and different planets, moons, etc. I took this to mean that some of the warrens, at least, are other planets. Is the "real world" (the mortal realm that encompasses the Seven Cities continent, Quon Tali, etc) itself a warren?

Probably.

I mean the demon warren, are basically demon worlds

 

[Clansman]

Is our world a Warren? Oh, crap. we're done.

not until some 'demon' learns how to summon us, bind us to his will, and forces us to do battle with each other by reciting cheesy lines.

I think the answer is yes. From what I understand all the warrens are basically worlds where the other races came from. I'd imagine if they remained in their world, they could probably develop the ability to draw power from the "real world" as if it was just another warren.
